hiho@ll

the topic says it all

why i ask:

i use sendmail to send some mails and i resolve the sendmail ID
through this ID i can check if the mail is queued locally (in /var/spool/mqueue)
or if it has been sent (trough /var/log/mail or mail.err or mail.warn)

the problem i have:
i have a relay point
this means if i send a mail from host1 it is relayed to host2 and then sent to the internet
the problem now is that host1 thinks the mail has been sent successfully because host2 accepted it for delivery

how can i check if the mail has really been sent?
maybe the sendmail ID is globally unique to a mail
so i can check the same sendmailID on host2

maybe someone knows another solution to this problem
(the question is: how can i track the mail status if the mail is relayed?)

btw.: how is the sendmailID and the messageID calculated?

thx@ll
